It was also insightful into the other candidates happily seeking to elevate themselves over Carson. This included Cruz.
Trump naturally is a good man.The others are so cranked about their personal egocentric paths, there is no room for kindness or gentlemanly conduct. For the others its all about the curtain call.

This is manners, in the old chivalrous way, putting others before oneself.In japan its called “reido.”
